Microchip Real Time Clock 64B Calendar DW:M:Y:LY, SPI Interface, 10-Pin MSOP Surface Mount MCP79521-I/MS

Microchip MCP79521-I/MS is a high-precision Real Time Clock (RTC) integrated circuit with 64 bytes of calendar memory. It provides comprehensive calendar functions including date format DW:M:Y:LY and time format HH:MM:SS:HSS, supporting day, week, month, year, and leap year adjustments. Packaged in a 10-pin MSOP surface mount, this device offers a compact footprint of 3mm by 3mm and a height of 0.95mm, suitable for space-constrained designs.

The device communicates via a Serial Peripheral Interface (SPI), enabling efficient and fast data transfers essential for embedded systems, industrial automation, and instrumentation where precise timing is critical. The MCP79521 operates over a wide temperature range from -40°C to 85°C, making it suitable for rugged and demanding environments.

Designed to work with a low minimum supply voltage of 1.8V up to a maximum of 3.6V, it ensures low power consumption ideal for battery-backed applications and longer device lifetimes. Though it does not meet automotive standards, it is a reliable choice for laboratory instruments, manufacturing control systems, and other commercial electronics.

The surface mount MSOP package supports automated PCB assembly, improving production efficiency and compactness. The robust calendar and timekeeping capabilities make the MCP79521-I/MS an excellent component for synchronizing events, logging data, and managing time stamping across a wide range of industrial and electronic devices.
